Grundfos 99490914 Pump
The Grundfos 99490914 is a professional-grade ALPHA1 26-99F high-efficiency circulator engineered for demanding hydronic heating and cooling applications. Built with a robust cast iron pump housing and an advanced ECM variable speed motor, this pump delivers a maximum head of 32.48 feet and a flow rate up to 26 GPM. Designed specifically for HVAC technicians, it features a 0-10V analog input for seamless integration into boiler management systems (BMS) and an alarm output signal for real-time diagnostics. The magnetite-resistant design and ceramic shaft ensure long-term reliability in systems prone to iron oxide buildup. This 115V single-phase unit utilizes a GF 15/26 flange connection, making it a drop-in replacement for the legacy 52722552 model. With a 360 mNm starting torque, the ALPHA1 26-99F circulator pump effectively clears debris and sediment, maintaining optimal system pressure and flow with minimal energy consumption.
Key Benefits
- System Integration: Externally controlled via a 0-10 VDC signal, allowing precise speed modulation by modern building controllers.
- Superior Reliability: Features a ceramic shaft and stainless-steel bearing plate to resist magnetite and system debris.
- High Torque Performance: 360 mNm starting torque prevents rotor seizing after seasonal shutdowns.
- Versatile Application: Suitable for radiant heating, fan coil units, and solar thermal systems with a wide liquid temperature range of 14°F to 203°F.
- Fail-Safe Logic: The pump defaults to maximum speed if the control signal is lost, preventing system freeze-ups or overheating.
Common Questions
What flange size does the ALPHA1 26-99F use?
This model utilizes a standard GF 15/26 flange with a 6-1/2 inch port-to-port length, compatible with standard 1-1/4 inch piping connections.
Can this pump be used in open-loop potable water systems?
No, the 99490914 features a cast iron housing designed for closed-loop heating and cooling. For domestic hot water recirculation, a stainless steel model is required.
Does it require external motor protection?
The electronically commutated motor includes internal thermal protection, eliminating the need for additional external motor starters or overloads.
